BACKGROUND OF THE INVENTION

1. Field of the Invention

The present invention relates to a liquid crystal display device (LCD),and more particularly, to a multi-domain liquid crystal display devicehaving color filter layer with electric field-distorting holes and asubsidiary electrode on an lower substrate to distort electric field andmethod of manufacturing thereof.

2. Description of the Related Art

Recently, an LCD has been proposed where the liquid crystal is notaligned, and the liquid crystals are driven by side electrodes insulatedfrom pixel electrodes. FIGS. 1A and 1B are sectional views of a pixelunit of conventional LCDs.

In the conventional LCD, a plurality of gate bus lines arranged in afirst direction on a first substrate and a plurality of data bus linesarranged in a second direction on the first substrate divide the firstsubstrate into a plurality of pixel regions. A thin film transistor(TFT) applies an image signal delivered from the data bus line to apixel electrode 13 on a passivation layer. The TFT is formed on eachpixel region and comprises a gate electrode, a gate insulator, asemiconductor layer, a source electrode, a drain electrode, etc.

The passivation layer is preferably formed over the whole firstsubstrate. The pixel electrode 13 is coupled to the drain electrode onthe passivation layer. Side electrode 15 is formed in a region except aregion where pixel electrode 13 is formed on the passivation layer.

On the second substrate, a light shielding layer 25 is formed shieldinglight leakage from the gate bus line, data bus line, and TFT. A colorfilter layer 23 is on light shielding layer 25. A common electrode 17 ison color filter layer 23. A liquid crystal layer is between the firstand second substrates.

A side electrode 15 and an open area 27 of the common electrode 17distort the electric field applied to the liquid crystal layer. Then, ina unit pixel, liquid crystal molecules are variously driven. This meansthat when voltage is applied to the LCD, dielectric energy due to thedistorted electric field arranges the liquid crystal directors in aneeded or desired position.

However, to obtain a multi-domain effect, open area 27 in commonelectrode 17 is necessary, which requires patterning of the commonelectrode 17. Moreover, if the electrodes do not have an open area orthe width thereof is narrow, the distortion of electric field needed todivide the pixel region becomes weak. Then, when voltage over athreshold voltage, V_(th), is applied, the time needed for the liquidcrystal directors to become stable increases.

Hereinafter, the multi-domain liquid crystal display device and methodfor manufacturing the LCD of the present invention is explained indetail by accompanying the drawings.

FIGS. 2A, 2B and 3A, 3B are sectional views of the multi-domain liquidcrystal display devices according to the first and second embodiments.

Referring to FIGS. 2A, 2B and 3A, 3B and as shown in FIG. 5A, forexample, the present invention comprises first and second substrates, aplurality of gate bus lines 1 arranged in a first direction on the firstsubstrate and a plurality of data bus lines 3 arranged in a seconddirection on the first substrate, a TFT, a passivation layer, and apixel electrode.

Data bus lines 3 and gate bus lines 1 divide the first substrate into aplurality of pixel regions. The TFT is formed on the each pixel regionand comprises a gate electrode 11, a gate insulator, a semiconductorlayer 5, an ohmic contact layer, and source/drain electrodes 7, 9. Thepassivation layer is preferably formed through the whole firstsubstrate. A pixel electrode 13 is coupled to drain electrode 9 andoverlaps the TFT and/or data bus lines 3, and gate bus lines 1 on thepassivation layer.

Also, the present invention comprises a light shielding layer 25 whichshields light leakage from gate bus line 1, data bus line 3, and TFT. Acolor filter layer 23 on light shielding layer 25. A common electrode 17with electric field-distorting holes or recesses 19 is on color filterlayer 23. A liquid crystal layer is between the first and secondsubstrates. Although FIGS. 2 and 3 show recesses 19, the recesses 19 maybe replaced by a hole in the color filter to expose the substrate.

As a modification, the second embodiment of shown in FIGS. 3A and 3Bfurther comprises a subsidiary electrode 15 on the passivation layer ina region except a region where the pixel electrode is not formed.

FIGS. 9A to 9F are sectional views showing the manufacturing process ofthe multi-domain liquid crystal display device according to the presentinvention, and FIGS. 10A and 10B are sectional views taken along thelines A-A' and B-B' of FIG. 7A.

To manufacture the LCD, in each pixel region on the first substrate, aTFT is formed comprising gate electrode 11, gate insulator 35,semiconductor layer 5, ohmic contact layer 6 and source/drain electrodes7, 9. At this time, a plurality of gate bus lines 1 and a plurality ofdata bus lines 3 are formed to divide the first substrate into aplurality of pixel regions.

Gate electrode 11 and gate bus line 1 are formed by sputtering andpatterning a metal such as Al, Mo, Cr, Ta, or Al alloy, etc. The gateinsulator 35 is formed by depositing SiN_(x) or SiO_(x) using PECVDthereon.

The semiconductor layer 5 and the ohmic contact layer 6 are formed bydepositing with PECVD (Plasma Enhanced Chemical Vapor Deposition), andpatterning amorphous silicon (a--Si) and doped amorphous silicon (n⁺a--Si), respectively. Also, gate insulator 35, amorphous silicon(a--Si), and doped amorphous silicon (n⁺ a--Si) are formed by PECVD andpatterned.

Data bus line 3 and source/drain electrodes 7, 9 are formed bysputtering and patterning a metal such as Al, Mo, Cr, Ta, or Al alloy,etc. At this time, A storage electrode 43 is additionally formed in thepixel region on the gate bus line 1 at the same time, the storageelectrode 43 makes a storage capacitor with gate bus line 1.

Subsequently, passivation layer 37 is formed with BCB(BenzoCycloButene), acrylic resin, polyimide based material, SiN_(x) orSiO_(x) on the whole first substrate 31. Pixel electrode 13 is formed bysputtering and patterning a metal such as ITO (indium tin oxide). Acontact hole 39 is formed to connect the pixel electrode 13 to the drainand storage electrodes 9, 43 by opening and patterning a part of thepassivation layer 37 on the drain electrode and storage electrode.

Pixel electrode 13 is formed by depositing using a sputtering andpatterning technique a metal such as ITO (indium tin oxide), Al or Cr.It is also possible to form pixel electrode 13 by patterning the samemetal once or by patterning different metals twice.

In the case of forming subsidiary electrode 15, when pixel electrode 13is formed, subsidiary electrode 15 is preferably patterned at the sametime.

When the subsidiary electrode 15 and pixel electrode 13 are formed withthe same material, the subsidiary and pixel electrodes aresimultaneously formed with one mask and the subsidiary electrode isconnected electrically to common electrode 17. Alternately, it ispossible to form them with different materials or double layer withadditional masks.

To apply a voltage (e.g., V_(com)) to subsidiary electrode 15, anAg-dotting part is formed at each corner of the driving area on firstsubstrate 31, electric field is applied to second substrate 33, and theliquid crystal molecules are driven by the potential difference. Avoltage (V_(com)) is applied to subsidiary electrode 15 by connectingthe Ag-dotting part to the subsidiary electrode, which is preferablyaccomplished simultaneously when forming the subsidiary electrode.

In the second substrate, color filter layer 23 is formed as R, G, B(Red, Green, Blue) elements which are repeated for each pixel. Ingeneral, to fabricate a color filter layer, a dyeing method or adispersing method is used, which is divided into a method for dyeing ordispersing a dyestuff or dye material, and a method for dispersing apigment.

The dyeing method for dye material comprises exposing and developingdyeable and photosensitive resin on a transparent substrate, and dyeingthe resin with a dyeing solution. The dispersing method for dye materialcomprises etching a polyimide layer dispersed with dyestuff using aphotoresist. The dispersing method for pigment comprises depositing aphotosensitive material dispersed with pigment on a photosensitiveresin, then exposing, and developing. Alternatively, the dispersingmethod for pigment comprises etching a non-photosensitive materialdispersed with pigment on polyimide with a photoresist.

FIGS. 4A to 4F are views showing the formation of a color filter layeraccording to the present invention. A light shielding layer 25 is formedon a substrate 8 (refer to FIG. 4A), a dyeable photosensitive layer 14is deposited thereon (refer to FIG. 4B), and a front exposure isperformed with a mask 10 (refer to FIG. 4C). The mask has various shapesof slits which allows electric field-distorting portions such as holesor recesses to be patterned at the same time. That is, color filterlayer 23 is patterned to have electric field-distorting holes 19 (referto FIG. 4D), and dyed with a suitable dye material (R, G, B)(refer toFIG. 4E). This process shown in FIGS. 4B to 4E is repeated to form thecolor filter elements (R, G, B) on the substrate (refer to FIG. 4F).

Common electrode 17 is formed following the contours of color filterlayer 23 including the recesses or holes 19 by depositing ITO preferablyusing a sputtering and patterning technique on color filter layer 23.Accordingly, the common electrode 17 also includes recessescorresponding to the recesses of the color filter layer. The liquidcrystal layer is formed by injecting liquid crystal between the firstand second substrates.

The liquid crystal layer may include liquid crystal molecules havingpositive or negative dielectric anisotropy. Also, the liquid crystallayer may include chiral dopants.

The common electrode 17 is formed along the surface of color filterlayer 23, and due to the electric field-distorting recesses or holes 19of color filter layer 23, a multi-domain effect is produced. That is, aresponse characteristic is improved by forming color filter layer 23 tobe about 1.0˜2.0 micrometers in thickness. The electric field distortingeffect is increased by the electric field-distorting recesses or holes19, which stably align the liquid crystal molecules. Accordingly, themulti-domain effect is enhanced.

On at least one substrate, a compensation film 29 is formed withpolymer. The compensation film is preferably a negative uniaxial film,which has one optical axis, and compensates the phase difference of thedirection according to viewing-angle. Hence, it is possible tocompensate effectively the right-left viewing angle by widening the areawithout gray inversion, increasing contrast ratio in an inclineddirection, and forming a multi-domain pixel.

In the present multi-domain liquid crystal display device, thecompensation film may be formed by a negative biaxial film with twooptical axes and wider viewing angle characteristics as compared withthe negative uniaxial film. The compensation film may be formed on bothsubstrates or on one of them.

After forming the compensation film, a polarizer is formed on at leastone substrate. At this time, the polarization axis of the polarizer is45°, 135° against the alignment axis of the liquid crystal molecules,and the compensation film and polarizer are preferably made as one.

Two domains are obtained by patterning electric field-distorting holes19 horizontally, vertically, and/or diagonally, as shown in FIGS. 5A to5D, or as shown in FIGS. 6A to 6C. A multi-domain may be obtained bypatterning electric field-distorting holes 19 to four domains using "+","x", or double "Y" shapes.

FIGS. 7A to 7E and FIGS. 8A to 8D are plan views of the multi-domainliquid crystal display device according to different embodiments of thepresent invention.

In the LCD of FIGS. 7A to 7E, subsidiary electrode 15 and pixelelectrode 13 are separated by a passivation layer as an intermediate,which prevents gate bus line 1 and data bus line 3 from interfering withthe distorted electric field of subsidiary electrode 15.

The passivation layer 37 includes a material such as SiN_(x) or SiO_(x).Moreover, if subsidiary electrode 15 and pixel electrode 13 overlap theTFT and/or data bus line 3, crosstalk is generated. Therefore,subsidiary electrode 15 and pixel electrode 13 are preferably formed tonot overlap using the passivation layer 37 as an intermediate or buffer.

As alternative embodiments to FIGS. 7A and 7B, in the LCD of FIGS. 7Cand 7D, the subsidiary electrode 15 is formed only at the side of thedata bus line 3, while in the LCD of FIG. 7E, the subsidiary electrode15 is formed only at the side of the gate bus line 1.

In the LCDs of FIGS. 8A to 8D, the passivation layer includes BCB(benzocyclobutene), acrylic resin, polyimide compound, and othersuitable low dielectric compounds as an organic insulator. Hence, thesubsidiary electrode 15 on the side of data bus line 3 may be formed onanywhere on the data bus line 3 to improve the aperture ratio. Moreover,since the subsidiary electrode 15 may be formed anywhere on the data busline 3, the pixel region may become broader than the LCDs shown in theFIGS. 7A to 7D.

As alternative embodiments to FIGS. 8A and 8B, in the LCD of FIG. 8C,the subsidiary electrode 15 may be formed any place on the data bus linebut only at the side of the data bus line 3, while in the LCD of FIG.8D, the subsidiary electrode 15 may be formed any place on the gate busline but only at the side of the gate bus line 1.

Furthermore, in the present LCD, an alignment layer(not shown in thefigure) is formed over the whole first and/or second substrates. Thealignment layer includes a material such as polyamide or polyimide basedmaterials, PVA(polyvinylalcohol), polyamic acid or SiO₂. For rubbingtreatments to determine an alignment direction, it is possible to applyany material suitable for the rubbing treatment.

Moreover, it is possible to form the alignment layer with aphotosensitive material such as PVCN (polyvinylcinnamate), PSCN(polysiloxanecinnamate), and CelCN (cellulosecinnamate) based materials.Any material suitable for photo-alignment may be used.

Irradiating light once on the alignment layer determines the alignmentor pretilt direction and the pretilt angle. The light used in thephoto-alignment is preferably light in a range of ultraviolet light, andany of non-polarized light, linearly polarized light, and partiallypolarized light can be used.

In the rubbing or photo-alignment treatment, it is possible to apply oneor both of the first and second substrates, to apply differentaligning-treatment on each substrate, or only to form the alignmentlayer without the alignment-treatment.

From the alignment-treatment, a multi-domain LCD is formed to have atleast two domains. LC molecules of the LC layer are aligned differentlyfrom one another on each domain. That is, the multi-domain is obtainedby dividing each pixel into four domains such as a "+" or "x" shape, ordividing each pixel horizontally, vertically, and/or diagonally, anddifferently alignment-treating or forming alignment directions on eachdomain and on each substrate.

It is possible to have at least one domain of the divided domainsunaligned. It is also possible to have all domains unaligned.

It is possible to apply the LCD of the present invention to anyalignment and mode including, for example, (1) a homogeneous alignmentwhere liquid crystal molecules in the liquid crystal layer are alignedhomogeneously to surfaces of the first and second substrates, (2) ahomeotropic alignment where liquid crystal molecules in the liquidcrystal layer are aligned homeotropically to surfaces of the first andsecond substrates, (3) a tilted alignment where liquid crystal moleculesin the liquid crystal layer are aligned tiltedly to surfaces of thefirst and second substrates, (4) a twisted alignment where liquidcrystal molecules in the liquid crystal layer are aligned twistedly tosurfaces of the first and second substrates, and (5) a hybrid alignmentwhere liquid crystal molecules in the liquid crystal layer are alignedhomogeneously to surface of one substrate between the first and secondsubstrates and are aligned homeotropically to surface of the othersubstrate.

Consequently, since the present LCD includes a color filter layer withelectric field-distorting holes or recesses and the common electrode isformed along the surface of the color filter layer, electric fielddistortion is induced. Moreover, this process of the present inventionis a simplified process which still maximizes the multi-domain effect toobtain a wide-viewing angle.

When conducting an alignment treatment, a rapid response time and astable LC structure can be obtained by the formed pretilt and anchoringenergy. Moreover, since the present invention forms a slit in theconventional mask and the electric field-distorting holes are formed bythe slitted mask on the color filter layer, it is possible to omit thepatterning process of the common electrode, such as shown in FIGS. 1Aand 1B, for example.

It will be apparent to those skilled in the art that variousmodifications can be made in the multi-domain liquid crystal displaydevice and method of manufacturing of the present invention withoutdeparting from the sprit or scope of the invention.
